Answer:
f(5) = -11
Step-by-step explanation:
Given that,
f(x) = 4-3x ....(1)
We need to find the value of f(5).
Put x = 5 in equation (1)
f(5) = 4-3(5)
= 4-15
= -11
So, the value of f(5) is equal to -11.

explain your thinking
Answer:
86
Step-by-step explanation:
Step 1: Collect liketerms by switching to the terms tgat are alike to the other sideb=12+74
NOTE: while switching, the signs change to the oppositeStep 2: Add 12 + 74b=12+74
b=86
Answer:
B=86
Step-by-step explanation:
So first step is add 74 to 12 because if you subtracted b with 74 and to reverse that you have to add and 74+12=86 and that is what b equals

Find the volume of the figure below. 5 cm 11 cm 66 cm 82.5 cm 132 cm 165 cm
Answer:
A) 66cm³
Step-by-step explanation:
Using the Pythagorean Theorem, the base of the triangle is 4. The area of a triangle is 1/2 base times height. Then you multiply times 11 to get the volume.
1/2(3)(4)(11)=66

The population of deer forest is currently 800 individuals. Scientists predict that this population will grow at a rate of 20 percent per year.
Answer:
C. 3.8 years
Step-by-step explanation:
Exponential Growth
The natural growth of some magnitudes can be modeled by the equation:
[tex]P(t)=P_o(1+r)^t[/tex]
Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The actual population of deer in a forest is Po=800 individuals. It's been predicted the population will grow at a rate of 20% per year (r=0.2).
We have enough information to write the exponential model:
[tex]P(t)=800(1+0.2)^t[/tex]
[tex]P(t)=800(1.2)^t[/tex]
It's required to find the number of years required for the population of deers to double, that is, P = 2*Po = 1600. We need to solve for t:
[tex]800(1.2)^t=1600[/tex]
Dividing by 800:
[tex](1.2)^t=1600/800=2[/tex]
Taking logarithms:
[tex]t\log 1.2=\log 2[/tex]
Dividing by log 1.2:
[tex]t=\frac{\log 2}{ \log 1.2}[/tex]
Calculating:
t = 3.8 years
Answer: C. 3.8 years
Answer:
3.5 years

What is the Mean Absolute Value?
Answer:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

(50 POINTS HELP)The manager of a restaurant chain wants to know how many times per month diners come to his restaurant. The table shows the number of visits in one month for three samples of 10 randomly chosen diners.
Answer the questions to find the means, compare the samples, and make a prediction.
1. What are the means of Samples 1 and 2? Show your work (what number did you use).
Write your answer in the space below.
The mean of sample 1 =
The mean of sample 2 =
2. What is the mean of Sample 3? Show your work (what number did you use).
Write your answer in the space below.
The mean of sample 3 =
3. Based on the data, would you predict that, in one month, the average diner would visit the restaurant fewer than 3 times, 3 or 4 times, or, about 4 times? Explain your reasoning.
Write your answer in the space below.
Answer:
Means
sample 1: 3.6
sample 2: 3.3
sample 3: 3.8
Step-by-step explanation:
Three or four times. All of these means are no less than three but no more than four this means that the average number of times is between three or four
a) The mean of the sample 1 = 3.6
b) The mean of the sample 2 = 3.3
c) The mean of the sample 3 = 3.8
d) In one month, the average diner would visit the restaurant 3 or 4 times
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the sample 1 be represented as M₁
Let the mean of the sample 2 be represented as M₂
Let the mean of the sample 3 be represented as M₃
where the number of visits to restaurant in one month is given by
Sample 1 = { 5 , 2 , 6 , 4 , 4 , 7 , 2 , 1 , 2 , 3 }
The number of visits = 10 visits
The total sum of sample 1 = 36
So , mean M₁ = 36/10 = 3.6
And , Sample 2 = { 2 , 6 , 1 , 3 , 4 , 5 , 2 , 1 , 5 , 4 }
The number of visits = 10 visits
The total sum of sample 1 = 33
So , mean M₂ = 33/10 = 3.3
And , Sample 3 = { 3 , 3 , 6 , 4 , 1 , 5 , 3 , 4 , 4 , 5 }
The number of visits = 10 visits
The total sum of sample 1 = 38
So , mean M₃ = 38/10 = 3.8
And , the average diner would visit the restaurant 3 or 4 times because the mean value of the three samples lies between 3 and 4
Hence , the mean of the sample is solved

the table gives information about the lengths of time spent in hours, some children spent watching Tv last week
The data in the table is plotted by using a histogram as shown in the diagram attached below.
What is a histogram?
A histogram can be defined as a type of chart that is used to graphically represent a group of data points (statistical information) into user-specified ranges through the use of rectangles.
Generally, the area of each rectangle is directly proportional to the data frequency and its width is equal to the class interval.
Given the following data:
Length of time (t) Frequency.
0 ≤ t < 10 810 ≤ t < 15 1515 ≤ t < 20 1020 ≤ t < 30 11The vertical axis (y-axis) of the histogram would be used to represent the frequency density while the horizontal axis (y-axis) of the histogram would be used to represent the lengths of time spent (in hours) spent by the children in watching Tv last week as illustrated in the diagram below.

She returns the 50 eels to the lake.
The next day Hannah catches 400 ells.
of these 400 eels, 10 are ringed
Work out an estimate for the total number
of eels in the lake.
Answer:
2000 eels
Step-by-step explanation:
Let us represent the total estimate of the eels = x
She returns the 50 eels to the lake.
The next day Hannah catches 400 eels, of these 400 eels, 10 are ringed.
To solve the above question, we have the following:
50/x = 10/400
Cross Multiply
10x = 50 × 400
x = 50 × 400/10
x = 2000 eels
Therefore, the total estimate of the eels in the lake = 2000 eels

The front of Rosie's house is similar in shape to the front of Sparky's doghouse. The base of the doghouse is 6 feet and the height is 5 feet. If the height of Rosie's house is 27.5 feet, what is the length of its base? If necessary, round your answer to the nearest tenth.
1. 22.9 ft pick and awnser!! :)
2. 28.5 ft
3. 33 ft
4. 30 ft
Answer:
33feet
Step-by-step explanation:
If the base of the doghouse is 6 feet and the height is 5 feet, we can write;
6 feet base = 5 feet height
To get the length of the base if the height is 27.5feet
x feet base = 27.5 feet high
Divide both expressions
6/x = 5/27.5
5x = 6 * 27.5
5x = 165
x = 165/5
x = 33ft
Hence the length of its base will be 33feet
